Someone over indulges at the curry house on sunday night, goes into work on Monday morning,fellow colleague begins to sniff loudly,"Phwoar who's followed through?someone must have,that's lingered for a good five minutes it stinks!!!"...meanwhile the main offender goes cheery red and decides not to own up and makes hasty retreat to the staff toilets.
